Whether the federal appeal remained admissible after the cantonal proceedings ended with a non-entry decision.
Solution extraite
The appeal became moot because the subject matter and any protected interest in review fell away once the cantonal instance issued its final non-entry decision.
Motifs extraits
With the final decision of the last cantonal instance, the dispute before the Federal Court and any interest in its adjudication ceased to exist; the case had to be struck from the docket.
